The true cosmic awareness alone gives Manny the advanny. So do the guidelines.

Manhattan is a true fifth dimensional being. What Cap Atom disintegrated on Mars is no more Dr Manhattan than a footprint is a boot. Cap Atom’s fifth dimensional existence is fragmented into separate selves such as Chrona Mota, which is seen in New-52 Captain Atom. He’s essentially an ant with a nuclear reactor, compared to Manhattan.

Mxy and Manny - I wonder what they would look like to each other? Morrison established in PE Action Comics that every ‘separate’ attack from a fifth dimensional imp is actually the same attack; from the point of view of the 5D being. I take this as meaning that they both have a similar worldview.

Mxy has been temporarily imprisoned in the regular 4D dimension by Manhattan’s agent, Mr Oz, so advantage Manhattan. Then again, Manhattan has been ‘beaten’ by an amoral human being, Ozymandias. Though Ozymandias only beat him using information that Manhattan, himself, supplied him with in Before Watchmen .
